Novel Fruit Hydrochars: Eco-Friendly Solutions for Waste Management in Electronics, Environment, and Agriculture

This research explores the potential of hydrochars obtained from diverse exotic fruit residues such as mango endocarps, mangosteen rinds, African oil palm residues, moringa husks and blackberry bushes, as materials suitable for insulation, dielectric applications and for potential agricultural purposes. The electrical properties of hydrochars derived from these residues reveal that these materials exhibit elevated dielectric constants and minimal electrical conductivities, rendering them well-suited for application as insulating materials. Furthermore, the study highlights the influence of fruit type, hydrothermal carbonization conditions, and post-treatment processes on the electrical characteristics of hydrochars. These research outcomes hold potential for advancing sustainable waste management practices promoting circular bioeconomy and circular engineering practices.
